Patent number: 4784349Abstract: The invention provides a yarn creel apparatus for the control of loose fly or lint formed when yarn is drawn from packages or cones (12) for use in a textile machine. The apparatus comprises a casing (10) within which the cones (12) are arranged on bobbin pins (11), air conduction means in the form of fans (17) to draw air into the casing from the surrounding atmosphere through at least one inlet comprising a filter panel (15) and then generally downwardly over the yarn cones to at least one outlet comprising filter panel(s) (16). The casing also houses yarn guide tubes (14) to guide yarn from the cones (12) upwardly within the casing tubes continuing through the casing wall to lead the yarns away from the apparatus. A self-cleaning version of the apparatus is also disclosed in which the filter panels (15,16) are replaced by an endless band of filter material (18) which is driven by rollers (21) past suction cleaning heads (22,23).Type: GrantFiled: September 25, 1987Date of Patent: November 15, 1988Assignee: Alan Shelton LimitedInventors: Kimberly J. Renwick, William E. A. Shelton

Patent number: 4773208Abstract: A process for operation of an approximately horizontal suction duct used for removal of broken fragments of thread or roving from a spinning machine and a suction apparatus for performing that process. In the process of my invention the suction capacity of the suction duct is made adjustable for joint adjustment of the suction at all of the suction intakes connected to it. Thus to reduce energy consumption this suction capacity can be set to a considerably lower value during normal operation than during doffing or batch changing where it is desirable to use the maximum rated suction capacity. The adjusting means for changing the suction capacity of the suction duct comprises advantageously a throttling means such as an automatically controllable plate mounted downstream from the suction intakes of the suction duct or a selector switch for providing different voltages to the winding terminals of an electric motor of an air blower mechanism to directly change the suction capacity.Type: GrantFiled: April 30, 1986Date of Patent: September 27, 1988Assignee: Zinser Textilmaschinen GmbHInventor: Horst Wolf

Patent number: 4757678Abstract: An open-end rotor spinning apparatus is provided which includes at least one spinning unit having yarn deflecting elements downstream from a yarn withdrawal duct. The yarn deflecting elements deflect yarn from the yarn withdrawal duct in a yarn spinning path. The yarn deflecting elements include at least one false-twisting edge. Yarn returning elements are provided for returning a yarn end to the yarn withdrawal duct past the yarn deflecting elements in a piecing path having a deflection less than the yarn spinning path deflection.Type: GrantFiled: November 5, 1987Date of Patent: July 19, 1988Assignees: Hans Stahlecker, Fritz StahleckerInventor: Fritz Stahlecker

Patent number: 4745738Abstract: An open end friction spinning apparatus is provided in which there are one or more spinning units with respectively two adjacently arranged rollers, rotating in the same direction, and disposed to form a wedge-shaped slot therebetween for accepting fibers and spinning them into a thread of yarn by a friction effect. Mechanical cleaning devices are provided for cleaning the surfaces of the rollers.Type: GrantFiled: January 20, 1987Date of Patent: May 24, 1988Inventor: Fritz Stahlecker

Patent number: 4744209Abstract: A device for removing residual fibers from perforated friction surfaces of an OE-friction spinning machine includes a suction device including a controllable cut-off element connected to a suction source, a suction tube section connected between the cut-off element and the friction surfaces, and a controllable compressed air connection disposed in the suction tube section.Type: GrantFiled: January 17, 1986Date of Patent: May 17, 1988Assignee: W. Schlafhorst & Co.Inventor: Heinz-Georg Wassenhoven

Patent number: 4729216Abstract: A service device in a ring spinning machine is moved after a yarn break to the appropriate spinning position to separate the broken yarn end from the winding by generating an air blast that acts on the yarn end. If the winding build-up is in a stage in which the initial winding cone has not yet been completed, the air blast is set at a high value so that a relatively strong separating force acts on the broken yarn end. If, on the other hand, the build-up of the winding cone has been completed, the separating force acting on the yarn end is less. The stage of the winding build-up is determined with the aid of a switch, which is connected to a stop member that contacts and rests on the ring rail of the spinning position. The setting of the two air blasts is performed by a switchable trottle.Type: GrantFiled: January 12, 1987Date of Patent: March 8, 1988Assignee: Zinser Textilmaschinen GmbHInventors: Joachim Rohner, Helmut Nickolay

Patent number: 4700538Abstract: Textile slivers tend to loose their cohesion when travelling over long distances from one piece of storage or processing equipment to another such piece of equipment. This problem is overcome by subjecting the sliver to a false twisting process during its travel, desirably by a pneumatic false twister located immediately adjacent to the sliver-receiving equipment.Type: GrantFiled: August 15, 1985Date of Patent: October 20, 1987Assignee: Carding Specialists LtdInventors: Andre Varga, Henry Cripps

Patent number: 4693069Abstract: A heat-insulating jacket extends around each rotating can of a doubling machine. Half way up the height of the can envelope surface, an extraction line for extracting the air heated by friction as the can rotates extends into the interior between the jacket and the can. The end-face boundaries of the rotating can and/or top and bottom closure members of the jacket are such that the pressures of the air drawn into the jacket are at least substantially equal at the top and at the bottom.Type: GrantFiled: September 3, 1986Date of Patent: September 15, 1987Assignees: Sulzer Brothers Ltd., Carl Hamel Spinn-& Zwirnmaschine AGInventors: Christian Imhof, Gerhard Kempf
